Found an independent up here who moves the favourite in every virtual race to the next full point.
If the jolly is 5/4, he pays out at 2/1.
Seems pretty fair, might spend a week in his shop so he changes his rules

What do they bet most of those races to? You got 11% in ur favour in that spot. Are there many dogs/horses between 11/10 and 6/4 for example in those races. I have never looked i assumed they were like 4/1 the field type races. getting 2/1 about a 5/4 poke must be + EV and makes you look like a mug to get on other stuff. most of the bets he lays at 10/1 and giving 11/1 won't give the punter the edge just a smaller negative edge. Wonder what he would lay on a 11/10 poke on the show which he pays 2/1 on.
Most are 3/1 - 4/1 the field, but they have a few 18 runner, 7/1 the field type races and a few 8 runner 5/4, 5/2, 10/1 bar two type.
Bet to around 112-115 in the 8 runner heats.
No idea what his limits are, guess I'll soon find out!
